Unplug your modem or router immediately for some time and then plug them back in. Well this problem is far less critical than the one signalled by this bug, because you can easily turn around by changing the UDP tunnelling port range in GNS3 preference.Restarting the Router/Modem will definitely resolve the Omegle Error Connecting to Server if it is caused due to a network connectivity issue. Once again, the under lying python3 library are not implemented in the same way than on BSD MacOSX I suppose. To be in gns3-1.5.2 release on my fedora 25,

On the other hand On my MacOSX El Capitan, with the release gns3-1.5.2, all is working fine. Can you imagine dynamips trying to talk with webmin perl proces ? A 'deaf Dialog' when we say in French !!!

# dnf install -enablerepo=updates-testing python3-async-timeout Once gns3-gui is open, with no project open ( so just only a process python3 corresponding to gns3-server ins running and listening on TCP port 8000), I ALWAYS GET a good result in Fedora 24, while gns3 fails in Fedora 25

But I don't know how to track this !ДЄdditionally, with selinux in permissive mode, or in enforcing mode, and firewall stopped or running, So the difference is more deeper in Python3 library. I tryed to rebuild on Fedora 25 the gns3-gui and gns3-server rpm packages, with the same ZIP original file and my spec file, but I get the same result than with the one coming from fedora standard repositoryД«ecause http_client.py, component of gns3-server use the pakage python3-aiohttp, I checked the release of this component. (in fedora 24 I installed the release from the original ZIP on github, and a *.spec file of my own. I'm trying to compare what is different between Fedora 24 and Fedora 25 environnement.
